PURPOSE: To reduce the man-hour, and to improve the productivity by integratedly and directly providing a fan member to either of a case forming a sealed container or a case cover to reduce the weight. CONSTITUTION: A temperature sensitive body 10 locked to the front face of a cover 3 senses the outside temperature, and opens/closes an oil feeding adjusting hole 5' through a connection rod. Transmission of the rotating torque from a rotary shaft body 1 on the driving side to a sealed container on the driven side is controlled by increasing/decreasing the effective contact area at a torque transmission chamber 4. In a fan member F made of the metal or the resin, either a case 2 forming the sealed container on the driven side or a case cover 3 is formed by the pressing of a metallic sheet, and a fan blade F of the fan member F is directly fixed to an extension part 2 which is integratedly extended outwardly from its outer circumferential part. Thus, the pressing of a spider, etc., as the fan member, and its fitting work can be fully dispensed with. |
